Abstract
The utility model relates to a double-end fixed wrench. The handle part of the utility model forms a bar-shaped N shape, one end head of the handle forms a shape of a duck egg circle, and the other end is an inner hole; both sides of the through surface of the inner hole are provided with a square nut, a hexagon nut, and arc ladder-shaped notches of screw bolt diagonal size series. The utility model can quickly screw in and screw off nuts and bolts with different specifications, so the defect that grouping spanners must be carried during outgoing operation can be avoided.
Description
A kind of double end back-up wrench, it relates to the back-up wrench of hand tools.
General double end back-up wrench is all made the single mouth of pulling, and it can only pull four directions and the hexagonal (hexagon)nut or the bolt of two kinds of different sizes, is one group with different size all in design in order to satisfy function of use, for selling or using.The user when desire to screw or when Panasonic's hexagonal (hexagon)nut or bolt at first rule of thumb range estimation judge the specification size and select the corresponding size spanner for use, usually cause and repeatedly choose repeatedly just and can finish, thereby cause inconvenience in the use, complete the carrying of palpus made this defective more outstanding when the instrument that particularly need carry was gone out operation.
The purpose of this utility model is to propose a kind of double end back-up wrench, and it can be used for the four directions of all size and hex bolts or nut and screws or unclamp, and overcomes to use the operation of must now judging and go out of existing spanner must carry the weak point of forming spanner.
The utility model is realized in the following way, plate shaped or handle two ends, the N word hole head of strip is the duck's egg circle, endoporus also is identical duck's egg circular hole, and its leptoprosopy both sides are made arcuation stairstepping notch by the diagonal-size of four directions and hexagon bolt nut by standard series respectively.
The advantage of this utility model is simple in structure, and it can screw or unclamp square and the hexagon bolt or the nut of all size quickly and easily, increase work efficiency, and the operation of having avoided the going out shortcoming that must carry into string wrench.
